In Vietnam, if you couldn't get PBR, there was the native brand Ba Mu'o'i Ba (Thirty-Three). It is said that to keep it from going bad in a tropical country with few refrigerators, formaldehyde was used as a preservative. The brew was even celebrated in song: Ba Mu'o'i Ba by Barry Sadler (1966).

"We put in just a touch of formaldehyde for flavor."

LOL. The formaldehyde rumor is current with the two best selling Thai beers, Chang and Singhai. Neither is particularly good beer.
